SMPP usage problem

hi,

we are trying to get an smpp (3.4) connection up and running with
kannel, but are having a few problems.

we are able to login correctly, send and receive the "enquire_link"
packets and receive SMS.  however, we are not able to send messages
using the sendsms interface.

when we send via the sendsms interface, this is the log output...

2003-03-13 17:26:55 [2] DEBUG: HTTP: Creating HTTPClient for
`127.0.0.1'.
2003-03-13 17:26:55 [3] INFO: smsbox: Got HTTP request

2003-03-13 17:26:55 [3] DEBUG: HTTP: Destroying HTTPClient for
`127.0.0.1'.

and that's it.  the bearerbox never seems to do anything with it.

here's our config:

group = smsc
smsc = smpp
smsc-id = smppTest
host = xxx.xxx.xxx.xxx
port = xxxx
smsc-username = xxx
smsc-password = xxxxxxxx
transceiver-mode = true
system-type = "VMA"
allowed-smsc-id = smppTest
address-range = ""

anyone have any ideas what we might be doing wrong?  

Thanks for any help,
Nick
